Mountain Dew is, in the USA at least, a highly caffeinated fizzy drink with a reputation
of being one of the potential drinks of choice to invigorate students needing to study all night. Exactly how something labelled "mountain dew", with
its connotations of purity and unadulterated fresh water, came to be used for a mind-altering drink compiled mostly of artificial ingredients is a mystery justified
only by the minds of teams of advanced marketing technicians with degrees in twisting consumer expectations for massive profit. (Edit: Apparently "mountain dew" is an old American slang term for moonshine, which was adopted by those clever marketing technicians specifically for the connotations of potency and rawness, rather than purity and wholesomeness that come to the minds of people not versed in this lore. Language can be strange sometimes.)

Interestingly, a product named Mountain Dew, also produced by the Pepsi-Cola Company, is also sold in Canada and Australia, but in both those countries
it has no caffeine whatsoever, and subsequently no reputation beyond "yet another bland, artificially flavoured, sickeningly sweet soft drink". This
rather devalues the mystique of the drink.
